Aardvark USB to I2C/SPI Interface

Aardvark USB to I2C/SPI Interface

Total Phase Aardvark USB to I2C/SPI Host Adapter
Total Phase Aardvark USB to I2C/SPI Host Adapter

The Total Phase Aardvark I2C USB to SPI Host Adapter is a perfect tool for every developer. This host adapter is a powerful and efficient tool that can be used by developers as a debugging tool. It works on I2C and SPI bus services and allows developers to connect it with Windows, Mac OS or Linux run computer systems via a fast USB connection. This interface allows users to downstream embedded system environment and transmit serial messages to the computer using SPI or I2C protocols.

The USB interface also provides scheduled updates of this adapter and makes it future-proof that are field-installable. The Total Phase Aardvark is cost-effective and very efficient for companies and organisations that are planning to increase their productivity.

  • Compatible with a wide range of specialist bus types (see Specification Tab)
  • Integates well into custom development solutions
  • Excellent value
  • Quantity discounts available
  • The Aardvark adapter is completely field-upgradable via USB

  • Power Management Bus (PMBus)
  • Smart Battery Bus (SBBus)
  • Intelligent Platform Management Interface (IPMI)
  • Two-Wire Interface (TWI)

Using an USB to I2C Host Interface and I2C Bus Analyser to Prototype Embedded Systems

This video demonstrates how an Aardvark I2C/SPI Host Adapter is used to stimulate an I2C target. The Beagle I2C/SPI bus analyser is used to monitor data being transfered between the host PC and the target.

Programming an I2C EEPROM using a USB to I2C Adapter

State Machine Matching Option

State Machine Matching Option

The Beagle 5000 Advanced State-based Matching Option provides developers with the ability to create complex, multi-state matches for either USB 3.0 or USB 2.0. When a match occurs, the match unit can have one or more defined actions such as trigger the capture, assert external output, filter out the matching data, or go to another state.



USB 5000 Multi-Analyser Option

USB 5000 Multi-Analyser Option

Certain applications require the use of multiple analyzers to monitor data. The multi-analyser synchronisation option allows developers to sync multiple analysers to measure latency and monitor data across an entire system with a level of precision previously unattainable.



SuperSpeed Downlink Option

SuperSpeed Downlink Option

The Total Phase TP322910 enables longer captures. Working with the real-time display feature, engineers don't have to wait for data to be captured and downloaded before viewing.
